TGC Talks: “Avoiding Penalties – 5 Common SARS Filing Mistakes Small Businesses Make”
Introduction: Compliance Is Cheaper Than Penalties
For many small businesses in South Africa, tax and compliance can feel overwhelming. Deadlines shift, documents pile up, and administrative demands compete with the real work of running a business. But here’s the truth most entrepreneurs only discover when it’s too late: non-compliance costs more than compliance — in time, stress, and money.
Every year, SARS issues thousands of penalties to SMEs for errors that could have been avoided with the right knowledge and processes. These penalties range from administrative fines to interest on late submissions, understatement penalties, and even the painful back-and-forth of audits triggered by avoidable mistakes.
At The Glass Castle (TGC), we regularly see the same compliance mistakes appear across startups, growing SMEs, and even established family-owned businesses. This article breaks down the five most common SARS filing mistakes, what causes them, how they impact your business, and — most importantly — what you can do to avoid them entirely.
Whether you’re handling your tax in-house or partnering with an accounting firm, avoiding these mistakes is one of the easiest ways to protect your cash flow, reduce risk, and keep SARS on your good side.
1. Missing Filing Deadlines (Even When No Tax Is Due)
The Most Common — and Most Costly — SARS Mistake
Small businesses often assume that if they had “zero activity” or “no tax due,” they do not need to file. Unfortunately, SARS does not see it that way. If you are registered, you must file — every period.
What Causes This Mistake?
• Forgetting annual or provisional deadlines
• Misunderstanding obligation triggers (e.g., thinking dormant companies don’t file)
• Relying on informal reminders instead of proper compliance tracking
• Handing tax responsibilities to staff without training or oversight
Why It Hurts Your Business
• Administrative penalties: SARS charges monthly penalties for every outstanding return, accumulating until the return is filed.
• Interest charges: For returns involving payments, interest continues to compound.
• Account locking: SARS may block refunds or freeze tax compliance status.
• Non-compliant TCC: Losing your Tax Compliance Status can sabotage tenders, funding, or supplier contracts.
How to Prevent It
• Implement a tax calendar that lists all deadlines for VAT, PAYE, income tax, and provisional tax.
• Assign responsibility clearly — and ensure that person is trained.
• Use accounting software reminders or automated filing alerts.
• Partner with a compliance team like TGC, who monitor and submit your tax obligations on schedule.
TGC Tip: Even if you missed a deadline, filing as soon as possible stops penalties from accumulating further.
2. Using Incorrect or Incomplete Financial Records
“We’ll Fix the Books Later” Is a Dangerous Approach
Sloppy bookkeeping is one of the fastest ways to trigger SARS flags and create reporting errors. When your records are not accurate, every return — VAT, EMP, or income tax — becomes a potential compliance risk.
Where Businesses Go Wrong
• Mixing personal and business expenses
• Not reconciling monthly
• Missing supporting documents
• Incorrect allocation of expenses
• Using outdated spreadsheets instead of cloud software
• Handing bookkeeping to untrained staff
Consequences You’ll Face
• SARS audit requests
• Understatement penalties
• Incorrect tax liability calculations
• Lost deductible expenses (paying more tax than needed)
• Delays in receiving refunds
How to Get It Right
• Keep business and personal finances separate at all times.
• Move to cloud-based accounting systems like Xero or Sage.
• Reconcile accounts monthly — not just at year-end.
• Standardise digital storage of every invoice, slip, and contract.
• Use a registered accountant to ensure accuracy.
TGC Tip: TGC offers monthly bookkeeping packages that keep your financials SARS-ready and audit-proof year-round.
3. Incorrect VAT Registration, Deregistration, or Return Filing
VAT in South Africa has strict thresholds and obligations, and even a small mistake here can result in harsh penalties.
Common VAT Mistakes We See
• Registering too late after passing the R1 million turnover threshold
• Voluntary registration without meeting the requirements
• Claiming VAT without proper tax invoices
• Not understanding zero-rated vs. standard-rated supplies
• Forgetting to deregister when revenue decreases
• Failing to submit VAT201 returns even for nil periods
Why VAT Errors Matter
SARS treats VAT non-compliance as a serious offence because it affects national revenue. VAT penalties can be severe, including:
• Up to 200% understatement penalties
• Interest on late payments
• Demand letters
• Loss of compliance status
• Possible SARS audits or site visits
How to Stay VAT-Compliant
• Track rolling 12-month turnover to anticipate mandatory registration.
• Ensure tax invoices meet SARS requirements.
• Maintain proper VAT category classification for every transaction.
• Review VAT returns before submission for accuracy.
• Consult with TGC if you’re unsure whether to register, deregister, or remain registered.
TGC Tip: Many SMEs lose money by incorrectly classifying zero-rated vs exempt goods. TGC helps you optimise VAT while remaining fully compliant.
4. Misreporting Payroll and PAYE
Your Employees Depend on Your Compliance
Payroll taxes are one of the biggest areas where SARS errors occur, mostly because payroll involves multiple moving parts — salaries, benefits, UIF, ETI, and monthly submissions.
Where Mistakes Happen Most Often
• Incorrect PAYE deductions
• Miscalculating bonuses or fringe benefits
• Failing to submit EMP201 and EMP501 reconciliations
• Not issuing IRP5s accurately
• Improper ETI claims
• Not updating employee changes
The Risks to Your Business
• SARS penalties and interest
• Employee disputes
• Non-compliance affecting tenders
• Delays in tax clearance
• Costly corrections for past periods
How to Avoid PAYE Mistakes
• Use professional payroll software
• Reconcile payroll monthly
• Verify all employee details and changes
• Avoid manual spreadsheets
• Outsource payroll to a specialist team
TGC Tip: TGC’s payroll team handles full monthly PAYE, UIF, and SDL compliance so your employees are always covered — and your records stay clean.
5. Not Seeking Professional Guidance Early Enough
The Most Preventable Compliance Mistake
Many SMEs only seek help from an accountant after something has already gone wrong — penalties, letters of demand, unexpected assessments, or SARS suspensions.
By then, fixing the issue is more expensive and stressful.
Why SMEs Delay Professional Support
• Trying to save costs
• Not knowing what they don’t know
• Thinking compliance is “simple”
• Underestimating risks of errors
• Fear of discovering deeper issues
Why Professional Guidance Matters
A strong accounting partner does more than “file tax forms.” They:
• Track deadlines
• Keep your records audit-ready
• Optimise your tax liability
• Advise on correct registrations
• Submit compliant returns
• Protect you from penalties
• Provide strategic financial clarity
